salas de chat online Most if not all of the web pages processed by a web browser contain links to external resources that need to be fetched prior to rendering the documents. Therefore, it is beneficial to send such links as early as possible in order to minimize the time spent until the browser becomes possible to render the document. Link header of type “preload” ([Preload]) can be used to indicate such links within the response headers of an HTTP response.dating games play online free

paginas de chat online However, it is not always possible for an origin server to send a response immediately after receiving a request. In fact, it is often the contrary. There are many deployments in which an origin server needs to query a database before generating a response. It is also not unusual for an origin server to delegate a request to an upstream HTTP server running at a distant location.dating role play games online

paginas de chat online en español The dilemma here is that even though it is preferable for an origin server to send some headers as soon as it receives a request, it cannot do so until the status code and the headers of the final HTTP response is determined.free dating websites reviews

paginas de chat online gratis argentina HTTP/2 ([RFC7540]) push can be used as a solution to the issue, but has its own limitations. The resources that can be pushed using HTTP/2 are limited to those belonging to the same origin. Also, it is impossible to send only the links of the resources using HTTP/2 push. Sending HTTP responses for every resource is an inefficient way of using bandwidth, especially when a caching server exists as an intermediary.free dating sites review

paginas de chat online hot This memo defines a status code for sending an informational response ([RFC7231], section 6.2) that contains headers that are likely to be included in the final response. A server can send the informational response containing some of the headers to help the client start making preparations for processing the final response, and then run time-consuming operations to generate the final response. The informational response can also be used by an origin server to trigger HTTP/2 push at an caching intermediary.partnersuche für über 40

chats para ligar gratis valencia A client MAY speculatively evaluate the headers included in the informational response while waiting for the final response. For example, a client may recognize the link header of type preload and start fetching the resource. However, the evaluation MUST NOT affect how the final response is processed; the client must behave as if it had not seen the informational response.persönliche partnervermittlung frankfurt

chats para ligar gratis barcelona An HTTP/1.1 client that mishandles the informational response as a final response is likely to consider all the responses to the succeeding requests sent over the same connection to be part of the final response. Such behavior may constitute a cross-origin information disclosure vulnerability in case the client multiplexes requests to different origins onto a single persistent connection.partnervermittlung luzern
